how do i parse header information from an mp3 file

goosefairy has asked for the wisdom of the Perl Monks concerning the following question:

It looks like MP3::Info will do it. Now, I just need to check with my boss and see if what he was asking for is what he wanted.

Thanks all.

Janitor note: Original content follows:

I need to be able to parse the information from an uploaded mp3 file to determine if it was encoded according to our specifications.

How do I go about doing this?

Use one of the modules, for example MP3::Info or AudioFile::MP3. If you want/need pure Perl, you can also decode the information manually, but as every mp3 file consists of many parts, all with their respective header (which makes such hacks as variable bitrate (vbr) possible), that's a tedious thing to do yourself.

You can also check the specification ID3 Tag Spec and roll your own. It's not hard for ID3v1. ID3v2 is a little more difficult. Grygonos	[reply]
